. Moore Observatory on the afternoon of February 27, 2007. This 185-degree fisheye view was recorded with a Nikon D70 and a Costal Optical Systems f/5.2 4.88 mm focal length lens. The roll roof building is in the center to the north, the RC24 dome is to the east on the right, and the CDK20 dome to the west on the left. Overhead the setting Sun is behind trees to the west, Venus visible here in the daytime is above the tree line near a contrail, and the Moon is rising over the RC24 dome to the east.

Next: Measuring aperture Up: Additional information Previous: Temperature and humidity . Some observatories have accurate information available on atmospheric pressure. If it is routinely available for every measurement, it should go in a column labelled PRESSURE, with the SI unit kPa. Note that pressures read from aneroid (dial-type) barometers are not very accurate, and probably should not be used. Only absolute pressures should be recorded, not values ``corrected to sea level''. ...

... Before the BATSE/GRO launch GRBs seem to be a uniform phenomenon with duration up to ~100 seconds. The BATSE has detected many events longer than 100 s and a few longer than 500s. We performed the off-line scan of the 1024 ms continuous BATSE records and revealed several non-triggered episodes of the BATSE GRB trigger which confidently belong to the same very long GRBs. ... These superlong GRBs probably belong to the class of ''long'' GRBs constituting the tail of their duration distribution. ...

... In addition, IZMIRAN comprises the St.Petersburg branch and magnetic ionospheric observatory in Kaliningrad. The history of IZMIRAN is largely that of investigating magnetic storms and sub-storms on the Earth surface, in circum-terrestrial and interplanetary space, initially by means of a network of ground stations of the Soviet Union (1930s - 1940s) and the nonmagnetic skunner "Zarja", then through the extensive use of magnetic measurements on artificial Earth satellites and automatic stations. ...

... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...
